Packet flow: FortiGates with NP6 processors first packet of a new session

Packet flow: FortiGates with NP6 processors first packet of a new session

On a FortiGate with NP6 processors the first packet in a new session is handled the same way as on a FortiGate with no NP6 processors. Except that some processes, such as DoS, ACL, IP integrity checking, and IPsec VPN decryption are accelerated by the NP6 processor.

Network processors (NP6)

FortiASIC network processors work at the interface level to accelerate traffic by offloading sessions from the main CPU. Current FortiGate models contain NP6 network processors. Older FortiGate models include NP4 and older network processors.
